U.S.–Iran tensions can be read through coercive diplomacy in which escalation functions as a tool to shape negotiations. Throughout the conflict, President Donald Trump applied intense military pressure on Tehran to raise the cost of defiance, followed by diplomatic engagement once leverage was established.
Recent developments suggest this approach has yielded results. By pairing military readiness with threats of destroying Iranian infrastructure, Trump pursued a policy of a managed force intensification to compress Iran’s bargaining position.
The fragile ceasefire already showed that the situation was becoming harder to control. A campaign initially framed as limited to degrading Tehran’s nuclear program risked pulling the wider region into the conflict. Iranian retaliation spread widely across the Persian Gulf, threatening U.S. military bases, striking regional energy infrastructure, and disrupting oil and food supplies – exposing the vulnerabilities of America’s regional partners.
Three dynamics sustained this cycle: widening conflict, mounting economic toll, and growing strain on U.S. alliances.
Iran’s horizontal escalation
In response to joint U.S. and Israeli strikes, Tehran adopted a strategy of horizontal expansion, broadening the battlefield by targeting U.S. military installations and civilian infrastructure across Qatar, Bahrain, the United Arab Emirates (UAE), Saudi Arabia, Iraq, and Kuwait.
These strikes exploited a key feature of America’s regional posture. The U.S. maintains a network of forward bases in allied countries to conduct operations in the Middle East. By threatening these facilities, Iran effectively turned the geography of U.S. alliances into a combat zone, placing American partners in harm’s way.
Throughout the crisis, both Washington and Tehran employed coercive signaling – calibrated shows of force and public warnings – to influence each other’s decisions. Trump’s threats and deadlines sought to compel compliance; Tehran’s attacks sent clear counter-signals of retaliation and cost.
Iran was unlikely to prevail in a conventional military confrontation with the United States. Its strategy instead focused on increasing the political, economic, and military costs for Washington and its partners. This in turn increased risks of spillover, including civilian harm, infrastructure damage, and broader regional entanglement.
Mounting economic shock
A second driver behind Trump’s pursuit of de-escalation has been the growing economic shock from the conflict that rippled through energy markets, supply chains, and global food systems.
One of the most sensitive chokepoints is the Strait of Hormuz – the narrow maritime corridor through which roughly one-fifth of global oil supply and a substantial share of seaborne fertilizers pass. The near-shutdown of this strategic waterway disrupted shipping flows and pushed up oil prices, fuel costs, and war-risk insurance premiums.
Iran’s asymmetric retaliation also crossed a line with its Gulf neighbors. After an Israeli strike hit Iran’s South Pars gas field — one of the world’s largest energy hubs — Tehran launched missile and drone attacks on key regional energy hubs.
These strikes inflicted widespread damage to Gulf energy assets such as knocking out 17% of Qatar’s LNG export capacity for three to five years. These attacks demonstrate that Tehran’s response extended beyond direct confrontation with U.S. forces to disproportionately impact regional economies and civilian infrastructure.
Had Gulf leaders not exercised restraint, Iran’s actions could have driven the Middle East to a broader regional war, although these strikes strengthened Tehran’s position by forcing Trump to limit U.S. involvement and bring the conflict to a close.
Beyond energy, the disruption threatened to squeeze the global food system. With about one-third of global seaborne fertilizers traded through the Strait, this could have triggered a food and humanitarian crisis in several regions.
Domestically, rising inflation, eroded consumer purchasing power, and the prospect of slower growth intensified political and economic pressure on Trump. The economic fallout extended to the Gulf, where Arab states have so far incurred up to $194 billion in losses, according to the United Nations Development Program.
Combined, these shocks reveal that coercive strategies generate leverage but also impose economic constraints.
U.S. allies bear the costs
The conflict strained America’s alliance network as well.
Countries hosting U.S. forces — including Qatar, Bahrain, and the UAE — faced direct security threats as missiles and drones traversed the region. For these governments, the danger of “entrapment risk” – the fear of being drawn into the conflict — increased pressure to limit further escalation and reassess the costs of forward deployment.
Tensions also surfaced within the transatlantic coalition. Several European nations hesitated to deploy warships to the Strait, with some denying the U.S. access to airspace or military facilities for operations, reflecting concerns about energy market instability and regional escalation.
At the same time, the White House indicated that the Trump administration could ask Arab countries to pay for the war, potentially shifting part of the burden onto regional partners. Yet as many Gulf states did not support the intervention and urged diplomacy beforehand, the prospect of being asked to absorb the consequences of a conflict they neither initiated nor endorsed would deepen unease among allies.
These dynamics nudged Trump toward capping the conflict.
The strategic gamble
Taken together, U.S.–Iran tensions could be best understood as a recurring system of coercive diplomacy in which force and negotiation acted as interconnected instruments of statecraft. The relationship has repeatedly oscillated between confrontation and limited engagement, without settlement.
Iran’s conventional military limits constrain its ability to compete directly with the United States; it retains leverage to threaten energy infrastructure, maritime security, and broader regional stability. These tools do not enable decisive victory, but they are sufficient to raise the costs of sustained pressure.
The result is managed instability: a system where coercion and engagement repeatedly rise and recede, producing stability through adjustment rather than resolution.
